  - Add `//noise2d` for perturbing terrain with multiple different noise functions
  - Add `//noiseapply2d` for running commands on columns where a noise value is over a threshold
  - Add `//ellipsoid2` which creates an ellipsoid that fills the defined region
+ - Add `//spiral2` for creating both square and circular spirals
  - Use [luacheck](https://github.com/mpeterv/luacheck) to find and fix a large number of bugs and other issues [code quality from now on will be significantly improved]
  - Multiple commands: Allow using quotes (`"thing"`, `'thing'`) to quote values when splitting
  - `//layers`: Add optional slope constraint (inspired by [WorldPainter](https://worldpainter.net/))

+Generates both square and circular spiral shapes with the given `<replace_node>`. The interval defines the gap between the spiral in nodes, and the acceleration defines by how much the interval should be increased (a value of 1 means 1 node per revolution).
